.net 操作sftp服务器

因为项目的需要，整理了一段C#操作sftp的方法。

依赖的第三方类库名称为：SharpSSH 1.1.1.13.

代码如下：

   1:  using System;

   2:  using System.Collections.Generic;

   3:  using System.Linq;

   4:  using System.Text;

   5:  using System.Collections.Specialized;

   6:  using System.Configuration;

   7:  using Tamir.SharpSsh;

   8:  using System.IO;

   9:  using Tamir.SharpSsh.jsch;
